Rise in CO2 has greened planet Earth

Surprise surprise…more CO2, more green planet. The alarmists seem to be quite upset about all the new greenery growing around the world as it doesn’t fit well with the IPCC-generated hysteria about harmful AGW.

We show a persistent and widespread increase of growing season integrated LAI (greening) over 25% to 50% of the global vegetated area, whereas less than 4% of the globe shows decreasing LAI (browning). Factorial simulations with multiple global ecosystem models suggest that CO2 fertilization effects explain 70% of the observed greening trend. – Zhu et al.
